Daniel Hilst bba6aeae1a refactor(build): reuse the shared git revision and epoch helpers
buildrpms.pl derived the git revision and SOURCE_DATE_EPOCH with its own inline
backticks while BuildUtils.pm already provided git_revision() and
source_date_epoch() for builddebs.pl. Both did the same thing, and the copies
in buildrpms.pl were the weaker ones: neither fell back to the tracked Gitinfo
and Gitepoch files, so a build from a source tarball with no git history
recorded the revision as "unknown" and stamped the current time as the build
epoch, losing reproducibility exactly where it matters most.

Verified that the helper returns the same revision and epoch as the code it
replaces on a checkout with history.

buildrpms.pl now loads BuildUtils.pm from its own directory, so the source-only
test stages the module into its sandbox alongside Version. That test copies the
builder rather than running it in the checkout, because it rewrites Gitinfo and
creates $HOME/rpmbuild before it looks at its arguments.

xCAT-test/unit

Unit tests. These run against the source tree only -- no xCAT installation, no running daemons, no management node.

They are executed on every pull request by the xcat_test GitHub Actions workflow, which calls run_unit_tests() in github_action_xcat_test.pl:

prove -r xCAT-test/unit

You can run exactly the same thing from a clean checkout:

cd <xcat-core checkout>
prove -r xCAT-test/unit

What belongs here

A test belongs in unit/ when everything it needs is in the checkout: plugin and library sources, kickstart/preseed/subiquity templates, postscripts, packaging metadata. Such a test asserts on rendered output or module logic and reaches the repository root through FindBin:

use FindBin;
use lib "$FindBin::Bin/../../perl-xCAT";
use lib "$FindBin::Bin/../../xCAT-server/lib/perl";

Because of those FindBin paths the tests only work from a source tree. The copy installed under /opt/xcat/share/xcat/tools/autotest/unit is not a substitute -- ../.. resolves to /opt/xcat/share/xcat/tools there and the tests die or silently skip. The CI takes a copy of the checkout before the build for this reason; see preserve_source_tree().

What does not belong here

Anything that needs an installed xCAT, a populated /install, a real service binary or a live daemon. Those go in ../integration and run on a management node through xcattest. Both suites run on every pull request -- the workflow installs xCAT on the runner and then runs the ci_test cases against it -- so putting a test in integration/ does not cost it CI coverage. What differs is what each suite is allowed to depend on, and that unit tests also run standalone from a bare checkout with no xCAT at all.

The distinction matters because a test that needs an absent environment does not fail -- it calls plan skip_all and reports as skipped. A handful of those in a suite of several hundred assertions is easy to stop reading. Keeping the two kinds in separate directories means a skip in unit/ is a real signal rather than routine noise.

Guarding on a source file, on the other hand, is fine and common here:

plan skip_all => "compute.subiquity.tmpl not found" unless -f $tmpl_path;

That guard never fires when the tree is intact.
